Adjust your monitor's color calibration; the XIV sunder definitely has a pair of orange stripes while the rest is a darker off-gray.
Huh? I didn't say it had no stripes.
Perhaps it's just that particular layout. As you probably already know, colours can "change" depending on what shades they are used against. Red amongst white looks different than red amongst black, for instance. It's your... well, my... eyes playing tricks.
The newer striped design is definitely an improvement though. When you put the Hammerhead next to the Sunder, you can see the difference greatly (someone else try this, so I don't look mad or like I'm being an arse lol). It's the more-defined lines and the original ship colour that "pokes" through and makes the striping "pop". Get what I mean?
Just thought I'd offer my opinion is all.
EDIT: Okay, this kind of explains it a little better. The two red circles show the difference in lines and seeing both side by side, you can see how much "darker" the Sunder looks in comparison due to the lack of lighter hull colour. And the orange striping is definitely a shade darker than on the Hammerhead.
Yeah, it's minor. I know that and it might not ever change. But as I said, I can't help but notice these things. I mean no disrespect or anything, so don't feel like I'm being overly critical. I love the ship sprites lol. I see some "cleaning-up" potential, is all.
